ASIFormDataRequest POST操作架构设计

ASIFormDataRequest的POST操作架构设计，方法由自己定义。

//开启iphone网络开关

[UIApplication
sharedApplication].networkActivityIndicatorVisible
=
YES;

ASIFormDataRequest
*request = [[ASIFormDataRequest
alloc]
initWithURL:[NSURLURLWithString:host]];

//超时时间

request.timeOutSeconds
=
30;

//定义异步方法

[request
setDelegate:self];

[request setDidFailSelector:@selector(requestDidFailed:)];

[request setDidFinishSelector:@selector(requestDidSuccess:)];

//用户自定义数据   字典类型  （可选）

request.userInfo = [NSDictionary
dictionaryWithObject:method
forKey:@"Method"];

//post的数据

[request
appendPostData:[body dataUsingEncoding:NSUTF8StringEncoding]];

//开始执行

[request startAsynchronous];

//执行成功

- (void)requestDidSuccess:(ASIFormDataRequest *)request

{

//获取头文件

NSDictionary *headers = [request
responseHeaders];

//获取http协议执行代码

NSLog(@"Code:%d",[request responseStatusCode]);

if
([delegaterespondsToSelector:@selector(OARequestSuccessed:withResponse:WithData:withHeaders:)])

{

//执行委托操作 
（架构设计   自选）

[delegate OARequestSuccessed:method withResponse:[request
responseString] WithData:[request responseData] withHeaders:headers];

}

//清空

if (request)

{

[request release];

}

//关闭网络

[UIApplication
sharedApplication].networkActivityIndicatorVisible
=
NO;
｝

//执行失败

- (void)requestDidFailed:(ASIFormDataRequest *)request{

//获取的用户自定义内容

NSString *method = [request.userInfo
objectForKey:@"Method"];

//获取错误数据

NSError *error = [request
error];

if
([delegate
respondsToSelector:@selector(OARequestFailed:withError:)])

{

//执行委托 将错误数据传其他方式（架构设计   自选）

[delegate OARequestFailed:method withError:error];

}

if (request)

{

[request release];

}

[UIApplication
sharedApplication].networkActivityIndicatorVisible
=
NO;

}

//执行成功函数

- (void)OARequestSuccessed:(NSString *)method withResponse:(NSString *)response WithData:(NSData
*)data withHeaders:(NSDictionary *)headers

{

NSString
*responseStr = [[[NSString alloc] initWithData:dataencoding:NSUTF8StringEncoding]
autorelease];

//服务返回post后的数据

NSLog(@"response:n%@",responseStr);

}

//执行失败函数

- (void)OARequestFailed:(NSString *)method withError:(NSError *)error

{

NSLog(@"Error:%@",error);

UIAlertView
*alert = [[UIAlertView alloc] initWithTitle:@"出错了"
message:@"网络连接失败,
请稍后重试." delegate:nil
cancelButtonTitle:@"好的"
otherButtonTitles:nil];

[alert show];

[alert release];
}
